Wrecking bar

ABSTRACT

A wrecking bar for disassembly of nailed wooden joints and other similar purposes. The bar is formed with an end shaped as a Ushaped hook, the end of which is shaped as a conventional tapered claw for use as a nail puller. A curved support section is fastened to the bar at the tangent point of the hook section and the straight bar section, with the support section mounted on the surface of the bar opposed to the hook section and with the axis of the support section perpendicular to the plane of the hook section and to the longitudinal axis of the bar. The support section is slightly curved with the ends of the support section each curving towards the handle end of the bar and with each end of the support section tapered to a chisel end. One such tapered end may be in the form of a conventional nail pulling pair of claws.

The bar is formed with an end shaped as a U-shaped hook, the end of which is shaped as a conventional tapered claw for use as a nail puller. A curved support section is fastened to the bar at the tangent point of the hook section and the straight bar section, with the support section mounted on the surface of the bar opposed to the hook section and with the axis of the support section perpendicular to the plane of the hook section and to the longitudinal axis of the bar.

The support section is slightly curved with the ends of the support section each curving towards the handle end of the bar and with each end of the support section tapered to a chisel end. One such tapered end may be in the form of a conventional nail pulling pair of claws.

BRIEF DESCRIPTION OF THE DRAWINGS The objects and features of the invention may be understood with reference to the following detailed description of an illustrative embodiment of the invention, taken together with the accompanying drawings in which:

FIG. 1 is a fragmentary perspective view of the working end of the invention;

FIG. 2 is a perspective view of the invention in use;

FIG. 3 is a perspective view of an alternate use of the invention; and

FIG. 4 is a sectional view of the bar, taken along line 4-4 of FIG. 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. I4 illustrate the improved wrecking bar which is formed as a conventional hooked bar 13 of octagonal section to which a support bar I2 is fixed. The hook section 14 terminates in tapered claws l6 separated by slot 21 and shaped for nail pulling and fitted with chisel edges 17. The support bar I2 is welded to the bar 13 near the point of tangency of the straight section 23 of the bar to the hook section 14 and mounted on a side of the bar away from the hook section 14.

The axis of support bar 12 is generally perpendicular to both the plane of the hook section 14 and the axis of the straight bar section 23, with the support bar 12 being somewhat curved with chisel end 26 and claw end 28 of the support bar pointing towards the handle portion 29 of the bar 10, so that the bar It) and hook section 14 may be rocked when the support bar is resting on a flat surface 36 as shown in FIG. 3.

As shown in FIG. 3, the support bar may be used as a pry member or as shown in FIG. 2, the support bar may be used as a support point against which to rotate the hook section 14 when prying sections 33 and 34 of nailed lumber apart.

Since obvious changes may be made in the specific embodiment of the invention described herein, such modifications being within the spirit and scope of the invention claimed, it is indicated that all matter contained herein is intended as illustrative and not as limiting in scope.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. An improved wrecking bar comprising a conventional straight bar having a handle at one end and terminating in a curved portion defining a hook shape, a curved working end with a support member having a working member formed at each end, said support member being joined to the straight bar near the general point of tangency of hook section to the straight section of the bar, said support member further extending along an axis generally perpendicular to the plane of the hook section and the axis of the straight section of the bar with the end thereof extending towards the direction of the handle.

2. The combination as recited in claim 1 in which the support member is joined to a surface of the straight bar which is on the exterior of the hook section.

3. The combination as recited in claim 1 in which each end of the support bar is shaped with a chisel edge.

4. The combination as recited in claim 3 in which one end of the support bar is fitted with two claw ends.
